Powering 3x 5m ws2812b (5V) + controller (7-12V) ?

-

hi everyone,

i'm new forum , arduino projects , have searched answer query.  can please tell me if i'm on right track here...


goal:  connect 3x 5m ws2812b (150 led version) in series = 450 leds = 22.5 amp potential max current

controller:  arduino uno (7-12v input, 5v output)

power supply: 5v dc, 30 amp.


newbie question: should attempt power 5v leds through arduino board (7-12v input, 5v output) or power board separately using low current 9-12v adapter , connect 5v, 30 amp power supply directly 3x ws2812 strips?

my rookie intuition tells me passing high current draw through board power leds not best solution.  secondly, cannot find 7-12v power supply high current (> approx 8 amps), seem indicate it's not idea.


ok found answer bit more searching.  need separate power supply led strips , use resistor + capacitor smooth power supply , reduce noise.

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp...
